Troubleshooting... first startup

Raptor13x · 06-15-2009, 07:32 PM

Just finishing up the BT 20v swap, and I'm working on troubleshooting the last few details. It's cranking but not starting right now.

I checked for spark- it has spark. I sprayed some starting fluid in to make sure it's not a fuel issue- still nothing. Compression is good.

Every once in a while, it sputters a bit and stalls out.

Any thoughts on what to check next?

Timing?

Raptor13x · 06-15-2009, 09:03 PM

hmm, I had the distributor off... I wonder if it can be installed backwards.

328FTW · 06-15-2009, 09:14 PM

I thought they were keyed one way though. They might not maybe my memory is wavering. They do have some adjustment though

I had this trouble on one engine and it was plugs. No idea why it was just a cold day and the slightly gunked plugs wouldn't let it start. Was annoying because it then started no problem after cleaning them and ran on those plugs trouble free for 2 years

I also once didn't plug in a map sensor and it did this.....yea whoops needed that

Raptor13x · 06-15-2009, 11:27 PM

If I don't hear from someone by tomorrow who knows for sure, I'll pull off the distributor and see if it's installed backward. As for the adjustment- it had a ridge where the bolt was before, so I just set the timing exactly as it had been.

Raptor13x · 06-16-2009, 01:17 AM

Okay, inspiration struck, so I went outside and confirmed that the distributor is indeed keyed, and can only be installed one way. I did, however, crank it over, and it sputtered a bit for a second before shutting off. I'm thinking it may be flooding the engine with fuel for whatever reason.

I'm using a map sensor off a 1990-93 Celica GT/GTS (5sfe). Any potential issues there?

Raptor13x · 06-16-2009, 08:53 PM

Thanks to some help from mr220v, I discovered there were two issues at hand- first, the injector resistor, and second, I had forgotten to install the Circuit Opening Relay, and had lost it.

So, a new relay is on the way, and in the meantime, because I hotwired the fuel pump to work, the car starts and runs!

I just bought some insurance, and I'm going to get a plate for it tomorrow I think! Insurance was hilarious- Progressive wanted $198/6 months, and every other company wanted $450-600/6 months. Hopefully I'll be selling the accursed Honda Civic sedan within a week!

Great job Raptor13x. Post some pictures of your ride/engine when you get it running the way you want.

muffinman · 06-17-2009, 11:43 AM

It's been so long that i thought you had just given up. Glad to hear you got it running.

You think it took him long, wait until I start working on mine! It will probably be classified as an antique before my 89 is running!

Raptor13x · 06-17-2009, 03:44 PM

haha... I had a lot going on over the past few months. Plus, it was a Michigan winter.. and I am sure as hell not gonna get my ass outside in -10 degree temperatures to wrench on a car.

On a separate note, I just had a shop cut out 2 inches of my shifter, and I installed a non-penis-shaped knob, so now it doesn't feel like I'm shifting a Ford F350 with a dildo mounted on top. I'll get pics after I a) get a license plate for it tomorrow, and b) give it a much-needed bath.

mr3 · 06-17-2009, 07:36 PM

Nah, dont wash her we wanna see some dirty pics.

How does one hot wire the fuel pump?

Raptor13x · 06-17-2009, 08:18 PM

Diagnostic connector- connect +B to Fp

fidget · 06-17-2009, 08:21 PM

Would this make it run full power all the time?

Raptor13x · 06-17-2009, 08:36 PM

No... it doesn't really make a noticeable difference from normal.

fidget · 06-17-2009, 08:43 PM

Works like a charm. Didn't help my issue at all though

back to the drawing board

Raptor13x · 06-17-2009, 08:58 PM

What's going on with yours?

Raptor13x · 06-19-2009, 09:15 PM

Okay, I took the car for its first real shakedown run and I've discovered a few things:

1) My exhaust is WAY too ****ing loud.

2) My aftermarket steering wheel needs a spacer for hand clearance from the turn signals.

3) The engine stumbles badly, especially at 2k-4k rpm. It's lessened somewhat if the throttle is kept near closed.
